SAP Note 12591 - Upgrade application server.

Symptom:

Upgrading application servers that do not run with the DB server in
a cluster

Cause and prerequisites

The upgrade only involves the central system.

Solution
Install the new versions of SAPR3_ORAEXE and SAPR3_SAPEXE on the
separate application server (see Upgrade Manual).

To upgrade to the new kernel, you have to change the
sap__profile:sap__exe.com
file. You can copy the current file from the central system.

You can delete the files in the exe directory of the old version
(see Upgrade Manual).
